WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent N 0. 710,345, dated September 30, 1902. Application led .Tune 20,1902. Serial No. 112.534. 2ND model.)

To all whom it may concern: Y

Be it known that we, THOMAS J. SWISHER, VICTOR A A. BURGnR,and EDWARD BURGER, citizens of the United States, residing at Kokomo, in the county of I'Ioward and State of Indiana, have invented a new and useful Vagon-Brake, of which the following is a specification.

The invention relates to improvements in wagon-brakes.

The object of the present invention is to improve the construction of vehicle-brakes and to provide a simple and comparatively inexpensive one of great strength and durability adapted to be readily applied to a wagon and capable of being lengthened and shortened when the running-gear of the wagon is adjusted and capable of automatic operation and of being locked out of operation when it is desired to back a vehicle.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure lis a plan view of a running-gear provided with a brake constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a detail view of the 'rockshaft. Fig. et is a detail view of the clamp. Fig. 5 is a detail view ofthe pivoted locking device for holding the brake out of operation when it is desired to back a vehicle. Fig. 6 is a detail View of one of the sections or members of the clamp.

Like numerals of reference designate corresponding parts in all the iigures of the drawings.

1 designates a transverse rock-shaft journaled in suitable bearings 2 of the rear bolster of a running-gear and provided at its ends with approximately L-shaped arms 3 and having a central depending loop 4, extending downward beneath the reach of the runninggear and connected with one ,member of an adjustable connection which extends forward to a point beneath the tongue. The outer portions of the arms 3 are threaded for the reception of nuts 5, which retain eyes 6Y of links 7 on the L-shaped arms, and these links 7 extend forward toa transverse brake-beam AS, which is mounted to slide on the rear portion of the reach and which is located above thesame and the rear hounds. The transverse brake-beam, which is provided at its ends with suitable brake-shoes, has a central depending loop or sleeve 9,l which receives the reach. When the rock-shaft is partially rotated, the brake-beam will be moved ba'ckward and forward to carry the brake-shoes into and out of engagement with the hind wheels.

The adjustable connection which extends from the rock-shaft to the tongue is composed of two telescoping sections or members 10 and 11, the section 10 consisting of a tube provided at its rear end with an eye 12, which receives the depending loop of the rock-shaft and which is preferably provided with ashank secured within the rear end of the tubular section 10; but any other form of eye may be employed. The section 1l, which consists of a rod, extends into the tubular section 10, and both sections are engaged by a clamp 13, composed of two blocks or members and provided with a longitudinal opening formed by grooves 14 and 15,0f different diameters, the front grooves 14. being of a size to receive the rod and the rear grooves being ofa size to receive the tubular section 10. 'Ihe sections or members of the clamp 13 are connected by screws or other suitable fastening devices, and they are firmly held in engagement with the rod and with Vthe tube. The sections or members of the clamp are also provided with transverse grooves 17, forming an opening vand adapted to permit the operater to see if the tubular section is properly engaged by the clamp. The clamp is adapted to secure the sections at any desired adjustment, and

the telescoping sections form an adjustable connection which is adapted to be varied in length as the running-gear is lengthened or shortened. n

The front end of the rod ll is provided with an eye 18, receiving the lower end 19 of a rod or bolt 20, extending downward from the rear portion of the tongue 2l of the running-gear and supported by an inclined brace 22. The rod or bolt is provided nearits lower end with a shoulder 23, against which the lower end of IOO the brace and the eye 1S abut, whereby the the same are prevented from working upward on the rod or bolt. The eye 18 is retained on the rod or bolt by a nut or other suitable fastening device, and the rear end of the tongue is slidably arranged between the front ends of the front hounds, which are connected by a top vplate 24 and by bottom pieces 25. The whililetrees are connected with the tongue by a pivot 26, extending through the doubletree and through the tongue and supported bya brace 27. When the tongue moves rearward between the front hounds by reason of the running-gear moving forward on the draft-animals in descending a hill or incline, the rock-shaft will bero- 'rated and the loop swung rearward, thereby swinging the arms of the rock-shaft backward and carrying the brake-shoes into engagemont with vthe rear wheels.

When it is desired to back the vehicle Without applying the brake, a pivoted locking device 28, which is mounted on the tongue in advance of the front hounds, is swung up- Ward into a position for engaging the same. The locking device, which is connected to a chain 29 or other suitable operating means, is approximately U-shaped, being composed of two L-shaped sides and a connecting transverse portion, and one of the sides is provided with an ear at its rear edge to receive one of the links of the chain. W'hen the locking device is swung upward, the transverse connection portion engages the lower face of the tongue, and the sides are located at opposite sides of the tongue.

It will be seen that the brakeis exceedingly simple and inexpensive in construction, that it is positive, reliable, and automatic in its operation, and that it is capableof adjustment to correspond to the adjustment of the running-gear-when the latter is lengthened or shortened.

What we claim isl. In a device of the class described,'the

`combination with a running-gear having a brake bar or beam, and an adjustable connection extending from the rock-shaft to the tongue and composed of telescopng sections, one of the sections being tubular and the other consisting of a rod, and a clamp composed of adjustable members having grooved inner faces, the grooves being of dierent diameters and receiving and engaging the rod and the tubular section of the connection, substantially as described.

y2. In a device of the class described, the combination with a running-gear having a sliding tongue, of an adjustable connection extending rearward from the tongue and composed of a rod, and a tube receiving the rod, a clamp composed of two sections or members provided at their inner faces with grooves of dierent diameters receiving the rod and the tube and engaging the same, and means for connecting the tube with brake-shoes, substantially as described.

3. In a device of the class described, the combination with a running-gear .having a sliding tongue, of a brake-beam having brakeshoes, ya rock-'shaft journaled on the rear portion of the running-gear and provided at its ends with arms connected with the brakebeam, said rock-shaft being also provided with a central loop, a tube or pipe secured to the loop, a rod telescoping in the tube or pipe, a clamp composed of sections or members having grooves of dierent diameters to receive the rod and the pipe or tube, a rod or bolt depending from the tongue and receiving the front end of the rod, aV brace supporting the depending rod or bolt, and means carried by the tongue for engaging the front hounds to lock the brake out of operation, substantially as described.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
